Hi everyone...
I had a bit of time over lunch yesterday to do some imaging and though the SOHO image of SpaceWeather did not show a lot of activity I was quite surprised at the views through the LS80T solar scope. Some beautiful filaments and active regions as well as a few proms visible to my eye.
I decided to do some testing of the full disk imaging through the double stacked LS80T/LS75FHa combo that has been my goto full-disk scope for many years. I have traditionally imaged with the ASI174MM camera, partially due to simplicity and partially due to artifacts in the ASI1600MM that I couldn't flat out and caused an ugly image. The smaller pixels in the 1600MM are a better fit to the short focal length of the LS80T, and I spent some time recently cleaning the camera and now able to produce a decent image. Examples of the image scale on the cameras is shown below.
The large disk was taken with the ASI1600MM with the equivalent of a 1.6x barlow threaded into the nosepiece. In the upper left is the 1600MM image at prime focus, and the lower left image is the image from the 174MM camera:
The image below is the FD composite using the ASI1600MM at prime focus:
After the full disk tests, I setup the Quark Combo with the ASI174MM to image through the Orion 130 EON since I have ignored this filter for some time and figured I better let in have some fresh air and sun I was running short on time, so I only grabbed a few images of the two main AR on the western side of the disk. The first used the 3x focal extender to give f21, which is below the preferred f-ratio for the filter but I wanted to see how it worked on the new OTA. Seeing was very poor and only captures of AR2847/2849 turned out very well:
The seeing seemed to stabilize a bit before i shut down, so I used the 5x Powermate to finish the tests off. This certainly seems to be a better setup at f35:
I nice day of experimenting
Brian

That's a nice experimental run of images, Brian.

Re: July 28th - Something Different
Hi Brian
Lovely images
I'm a bit confused though, in your text you say the large disk at 1.6x is with the ASI174, but on the image it says 1.6x is with the ASI1600, am I reading this wrong, I have just been to the dentist so a bit drugged up so could easily be me
Cheers Rod

Re: July 28th - Something Different
Thanks everyone for the comments and feedback on the images
Rod, you are correct...I miss typed the description and the 1.6x image was with the ASI1600MM. Sorry for the confusion, I have corrected it in the post.
